I’m assuming you mean an isolated ground, where the grounding back to the panel is separate for each outlet where two or more circuits share the same equipment (metal outlet boxes) grounds.
Yes, if you run a separate ground from the outlet to the panel, it will help things as far as stray voltage on the common grounds not affecting your equipment — which is the reason you find them on hospital equipment and computer servers.. For that to work, you will also have to buy an isolated ground receptacle that has insulators on the ears to decouple the outlet from the grounded box.
If you use romex with plastic boxes, then the romex ground and the non-conductive box acts like an isolated ground.
